Abstract (en)

[origin: WO9741420A1] A system for remote near infrared (NIR) spectral analysis of hydrocarbons using telecommunication optical fibers for real-time on-line transmission of NIR spectral information from an examined hydrocarbon sample to a remote analyzer including a light source (22) for generating near infrared radiation; an optical probe head (34) being at on-line contact with an analyzed hydrocarbon sample; at least one telecommunication transmitting optical fiber (36) for inputting the near infrared radiation into the optical probe head, such that the radiation passes at least once through the hydrocarbon sample, such that a spectrum of the sample is generated; a detector (42) for analyzing the spectrum, the detector and the light source being part of an analyzer (20); and at least one telecommunication receiving optical fiber (40) for receiving the radiation after the passing through the sample and inputting the radiation into the detector.
